Specific embodiment

A preferred embodiment is named, and completely illustrates the utility model in conjunction with attached drawing to become apparent from.

As shown in Figure 1 to Figure 2, the utility model provides a kind of food-grade flap valve comprising has valve body 1, valve plate 2 and drives Dynamic system 3, valve body 1 are tubular construction, and a upper flange plate 11 is arranged at top, and upper flange plate 11 and the external equipment of upstream pass through spiral shell Bolt is connected and fixed.The centre of surface of upper flange plate 11 has an opening, it is preferable that and it is a circular open, valve plate 2 is a metal plate, It is overlapped with the circular open of upper flange plate 11.The inner wall of circular open is inclined-plane, and top area is less than the area of lower section, valve plate The inner wall of 2 outer walls and circular open has the inclined-plane at identical inclination angle.The surrounding side wall of valve plate 2 and the inner wall of circular open closely paste It closes, and the flush on the surface of valve plate 2 and valve body 1.Using the opening at oblique angle can make the material medium of top device without Method is stuck in the position of circular open, then reaches better seal effect.

There is a ring annular groove on the surrounding side wall of valve plate 2, a round section joint ring 4 is set in annular groove, and " O " shape The height of circle 4 is greater than the height of annular groove.In the annular groove of valve plate 2 place round section joint ring 4 be in order to make valve plate 2 with it is upper Better tightness between the circular open of ring flange 11, when valve plate 2 closes at circular open, by squeezing round section joint ring 4, make there is no gap between valve plate 2 and circular open, it is therefore prevented that the dielectric leakage inside upstream equipment, i.e. sealing reach best.

Drive system 3 is mounted on the outer surface of valve body 1 comprising driving actuator 31, enabling axis 32 and adjusting bolt 33.Driving actuator 31 is fixed on the outer surface of valve body 1, for driving enabling axis 32 to be rotated.Drive actuator 31 logical External equipment access gas source is crossed, by the torque of a certain size pressure control enabling axis 32, to realize that the rotation of valve plate 2 is opened It closes, and is fitted closely with circular opening.It is existing how specific driving actuator 31 is belonged to by the rotation of pressure control enabling axis 32 Some technologies, therefore details are not described herein.

Backing plate 5 is installed between driving actuator 31 and valve body 1, backing plate 5 can first pass through bolt and be installed on valve body 1, and three Person passes through that bolt is stacked on top of each other to be fixedly connected again.Backing plate 5 can make to drive the connection between actuator 31 and valve body 1 more firm Gu and avoid that and actuator 31 will be driven to be directly installed on 1 surface of valve body to the generation destruction of valve body 1.

As shown in Figures 3 to 5, one end connection driving actuator 31 of enabling axis 32, the other end connect valve plate 2.Enabling axis 32 for being driven at the turning moment to valve plate 2 of driving actuator 31.Enabling axis 32 is connect with driving actuator 31 by spline Mode be fixedly connected.

There is a mounting hole on the side wall of valve body 1, enabling axis 32 is fixed in mounting hole.Enabling axis 32 and mounting hole it Between front-rear position at be respectively arranged with a material be Teflon axle sleeve 7, be used to support enabling axis 32, play substitution bearing Effect, and the material of Teflon can reduce the friction between enabling axis 32 and the inner wall of mounting hole, and torque is transmitted more, It is more wear resistant.The end that bolt 33 is located at close valve plate 2 on enabling axis 32 is adjusted, for adjusting and fixing valve plate 2 in enabling axis Position on 32, prevent valve plate 2 during operation makes the inside of the food-grade flap valve upper square object occur because being displaced The phenomenon that material leakage.

Have a dustband 6 at the inner surface of valve body 1, the aperture position of mounting hole, dustband 6 be fixed on enabling axis 32 with Between mounting hole, and in the end of mounting hole, for sealing mounting hole, when preventing valve plate 2 from opening, the subordinate out of upstream equipment Come material medium pour enabling axis 32 and axle sleeve 7 gap and wearing part.Preferably, the material of dustband 6 is rubber material Material, to play preferable sealing effect by certain self-deformation.

As shown in Figure 6 to 7, valve plate 2 includes cover board 21, drive rod 22 and fixing axle 23, and one end of drive rod 22 is welded In on cover board 21, the other end of drive rod 22 is welded in fixing axle 23.Fixing axle 23 is placed on one end of enabling axis 32, and passes through The keyway being set on enabling axis 32 is fixedly connected by way of being connect with the key in fixing axle 23 flat key.It is connected using flat key Mode install fairly simple, torque transmitting is preferable.Alternatively, it is possible to use other connection types.

When the food-grade flap valve is worked, in the state that valve plate 2 is closed, the outlet of the mixing plant of top and valve The mounting surface of plate 2 is concordant, so that the rotary part in upstream equipment exit is close to the operation of valve plate 2, realizes entirely without dead angle, keep away The phenomenon that having exempted from the presence of dead material.When material inside top device is discharged, valve plate 2 is controlled by driving actuator 31 32 Unscrew of enabling axis processed, top material carry out blanking, to blanking after, pass through driving actuator 31 control enabling axis 32 Valve plate 2 is closed in rotation, is closed the space inside valve body 1.

In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right", The orientation or positional relationship of the instructions such as "vertical", "horizontal", "top", "bottom", "inner", "outside" be orientation based on the figure or Positional relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or group of indication or suggestion meaning Part must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that This is merely illustrative of, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art Under the premise of without departing substantially from the principles of the present invention and essence, many changes and modifications may be made, But these change and modification each fall within the protection scope of the utility model.
